Add power steering fluid. The following is a related introduction about the power steering pump: Classification: Power steering systems can be roughly divided into three categories: mechanical hydraulic power steering systems, electro-hydraulic power steering systems, and electric power steering systems. The mechanical hydraulic power steering system is generally composed of components such as a hydraulic pump, oil pipes, pressure and flow control valve body, V-type transmission belt, and oil reservoir. Definition: The car power steering pump refers to a component that helps improve and stabilize car performance. It mainly assists the driver in adjusting the car's direction. Currently, most cars are equipped with power steering pumps, mainly including the steering power steering pump and the brake vacuum power steering pump.
I've been driving for decades and am quite particular about power steering fluid. Generally, you should add dedicated power steering fluid, or automatic transmission fluid (ATF) also works well, especially for older cars due to ATF's good compatibility. The key is to follow the vehicle manual's recommendations—never add the wrong fluid like engine oil or brake fluid, as that can wear out the power steering pump, leading to heavy steering, leaks, or even hose bursts. Regular fluid checks are crucial: inspect the level against the markings when the engine is cold before starting, ensuring it's within the middle range and not overfilled. If the fluid appears too dark or has a burnt smell, replace it. I recommend checking every two to three years to avoid failures while driving. Proper maintenance ensures smooth steering and extends the system's lifespan.
